<p>OK, I have updated the spreadsheet and put in my proposed milestones and other parts of my proposed plan (e.g., a public blog posting schedule).</p>

<p>The one item I'm rather nervous about is that according to the tracking doc we are considering reserving a new keyword with only five weeks left until the deadline, with no lang liaison or RFC proposed. In the aftermath of the 2018 edition we all seemed to agree that we pushed too many things to right before the deadline, and we should want to prevent a re-run of this by starting efforts like these well in advance.</p>
